SAFETY NOTICE:
	This script SHOULD NEVER EXIST on a Production Perforce server.

DESCRIPTION:
	This script simplifies the process of testing an SDP installation,
	repetitively blasting all process by the 'perforce' user and resetting
	the SDP from the ground up, blasting typical SDP folders each time.

	It is helpful when bootstrapping a demo server with a sample data
	set, complete with broker, and optionally Perl/P4Perl and
	Python/P4Python.

PLATFORM SUPPORT:
	This works on Red Hat Enterprise Linux, CentOS, and Mac OSX
	(Mavericks, Yosemitie, Sierra) platforms.  It works on RHEL/CentOS
	6.4-6.9 and likely on other Linux derivatives with little or no
	modification.

	It currently supports only the bin.linux26x86_64 (Linux) and
	bin.darwin90x86_64 (Mac OSX/Darwin) architectures.

REQUIREMENTS:
	Development utilities such as 'make' and the 'gcc' compiler
	must be installed and available in the PATH (unless running
	with '-fast').

	The 'curl' utility must be installed and available in the
	PATH (unless running with '-local').

OPTIONS:
 -B	Specify '-B' to blast base SDP dirs, for a clean start.
	Otherwise, downloaded components from earlier runs will
	be used (which should be fine if they were run recently).

	The '-B' and '-local' arguments are mutually exclusive.

 -local
	By default, various files and executables are downloaded from
	the Perforce Workshop or the Perforce FTP server as needed.
	With '-local', any missing files are treated as an error
	condition.

	The '-B' and '-local' arguments are mutually exclusive.

 -fast	Specify '-fast' to skip installation of Perl auxiliary things
	like Perl, Python, P4Perl, P4Python.

	The '-fast' argument changes the check for GCC/G++
	from a fatal error to a warning message.

 -no_ssl
	By default, the Perforce server is setup SSL-enabled.  Specify
	'-no_ssl' to avoid using SSL feature.

 -no_sd
	By default, the Perforce Sample Depot data set is loaded.
	Specify '-no_sd' to skip loading the Sample Depot.

 -p <dir1>[,<dir2>,...]>]
	Specify a comma-delimited list of directories under /p4/common
	to preserve that would otherwise be removed.  Directories must
	be specified as paths relative to /p4/common, and cannot contain
	spaces.

	For example, the value '-p config,bin/triggers' would preserve the
	/p4/common/config and /p4/common/bin/triggers directories.

	Directories specified are moved aside to a temporary working area
	before the SDP folders are removed.  After installation, they are
	moved back via an 'rsync' command with no '--delete' option.  This
	means any files that overlap with the stock install are replaced
	by ones that originally existed, but non-overlapping files are not
	removed.

	This is intended to be useful for developing test suites that
	install server under /p4/common/bin, e.g. Component Based Development
	scripts which install under /p4/common/bin/cbd would use '-p bin/cbd'.

 -b <branch>[,@cl]
	The default SDP install method is to clone the SDP from the main
	branch in The Workshop ($WorkshopPort).  Specify '-b' to use
	a different branch, e.g. 'dev'.

	If '-b' is specified with the optional @cl syntax, where @cl
	specifies a changelist with files shelved on the given branch,
	a form of unshelving is done, enabling a workflow for testing
	shelved changes with the Helix Installer.  So for example,
	specify '-b dev,@23123' to clone from the dev branch, and then
	followed by a fetch of shelved changelist @23123, which is
	expected to have files shelved in the dev branch.

 -t <tarfile>
	Specify a tarfile to use, e.g. '-t sdp.Unix.2017.3.23041.tgz', or
	use the special value '-t default' to use the default SDP tarfile,
	$SDPTar

	The specified tar file must exist here:
	https://swarm.workshop.perforce.com/projects/perforce-software-sdp/files/downloads

	If '-t <tarfile>' is not specified, default install method is
	used instead, which is to clone the SDP main branch from The
	Workshop ($WorkshopPort).

	Use '-t' to get a known version of the SDP for testing.  Avoid '-t'
	to test with the very latest SDP from a given branch (see '-b' above
	for more info), even if the latest has not yet been packaged into a
	distribution tar file.

 -D     Set extreme debugging verbosity.

HELP OPTIONS:
 -h	Display short help message
 -man	Display man-style help message

EXAMPLES:
	COMPREHENSIVE INSTALLATION:

	su -
	useradd perforce
    	mkdir -p /hxdepots/reset
	chown -R perforce:perforce /hxdepots/reset
	cd /hxdepots/reset
	curl -k -s -O https://swarm.workshop.perforce.com/downloads/guest/perforce_software/helix-installer/main/src/reset_sdp.sh
	./reset_sdp.sh 2>&1 | tee reset_sdp.log

	FAST INSTALLATION (skipping Perl, Python):
	su -
	useradd perforce
    	mkdir -p /hxdepots/reset
	chown -R perforce:perforce /hxdepots/reset
	cd /hxdepots/reset
	curl -k -s -O https://swarm.workshop.perforce.com/downloads/guest/perforce_software/helix-installer/main/src/reset_sdp.sh
	curl -k -s -O https://swarm.workshop.perforce.com/downloads/guest/perforce_software/helix-installer/main/src/r
	./r

	Note that the 'r' wrapper script calls the reset_sdp.sh script with
	a pre-defined of flags optimized for fast opreration.  The 'r' wapper
	also handles log capture, writing to the file 'reset.log'.

	SDP DEV BRANCH TESTING:
	The Helix Installer can be used to test SDP changes shelved to the SDP
	dev branch in The Workshop.  The following example illustrates testing
	a change in shelved changelist 23123:

	su -
	useradd perforce
    	mkdir -p /hxdepots/reset
	chown -R perforce:perforce /hxdepots/reset
	cd /hxdepots/reset
	curl -k -s -O https://swarm.workshop.perforce.com/downloads/guest/perforce_software/helix-installer/main/src/reset_sdp.sh

	./reset_sdp.sh -b dev,@23123 2>&1 | tee reset_sdp.CL23123.log

	After the first test, an iterative test cycle may follow on the same
	shelved changelist. For each test iteration, the shelved changelist
	is first updated in the workspace from which the change was originally
	shelved, e.g. with a command like 'p4 shelve -f -c 23123'.

	Then a new test can be done by calling reset_sdp.sh with the same
	arguments. The script will re-install the SDP cleanly, and then
	re-apply the updated shelved changelist.
